Originally Okrasa kits were in the following arrangements, the TS 1200, and
the TSV 1300/30. The TS-1200 included a pair of Okrasa twin-port cylinder
heads with twin port manifolds, two Solex 32PBIC carburators found on early
Porsche 356s, and specially designed linkage. The TSV 1300/30 Kit came with
the same parts as the TS 1200 and also included a 69.5mm chrome moly
crankshaft enlarging the capacity of the motor to 1295cc. Many other options
and installations could be done. Okrasa offered factory built up motors as
well.
